@zxbdragon 我有一个无关问题… 为什么之间交替中文跟英文? 英文词汇过少? 实践英文这儿吗?

Sorry.
My English is poor.
I am pressed for time as I have a lot of work to do. That's the way it is. .

不好意思,
我英文不太好。
我时间紧张,要做好多事(在中国才能生存)。就是这个原因

Maybe Contra has other names because of this.
Which kind of makes sense since Super Contra is called just Super C on the US.
That makes me think why the name Contra was chosen at first...
But again, this is just speculation with no trusted/official source at all.

edit: I've found this article, that the writer kind of says the same thing I tough.
But again, no official/trusted sources...

I'm not sure there's an official source, but that's always been the generally assumed reason I've seen everywhere all the way since back in the days. For both "Super C" and "Gryzor". I guess, "Probotector" too, but there's more to that one.

"Contra" standing in for the (Iran-)Contra debacle was well-known at the time. Heck, even as a kid, following the scandal in the news, I knew what Konami was referencing.

"Rush'n Attack" was a similar Konami pun. They knew what they were doing.

Also compare the title of the arcade game "Bay Route", by Sunsoft. Say it out loud.


(answer: Russian Attack. Beirut)

Wow, that "Beirut" one is completely impossible to get if you aren't a native English speaker - it never occured to me.

I also didn't realise the one in "Rush'n attack" until a few years ago when I said the title out loud. It's much more obvious though. "Green Beret" had its own more obvious problems of course.

Very interesting!!
I don't remember to have seeing this Iran/Contras scandal back in the day.
I do remember that I studied a little about the Somoza's, but I don't quite remember.

I guess back in the day there was a little more freedom on the game marked.
These kind of games certainly would scandalize some people today!

Doesn't a game named Guevara also exists?
I hear many people talking about Che Guevara, maybe they're related.

Yeah, Guevara, as it was titled in japan (and which obviously is about the cuban revolution) was retitled Guerilla to avoid controversy in the U.S.

I figured out "Russian attack" as a kid and thought it was a pretty clever kid. Then i grew up and it dawned on me that the whole game was pretty offensive. I mean, if you distil it, it's about the US surgically invading the USSR, all while the cold war was still in effect in the real world.

Both these games rely on a sort of cartoonification (out of necessity, it's old action games after all). In guevara, you literally play as castro and guevara making it look like they were the sole actors in the cuban revolution. These dudes seem nearly invincible, but and the game emphasises rescuing hostages by rewarding huge points for touching them but equally sever minus points for accidentally shooting them. In rush'n'attack, you're two grossly under-equipped commando soldiers taking on basically the whole red army. Both games feel kind of super hero-y. Power fantasies, essentially.

Guevara (or "Gebara" as it is often romanized) is an excellent game by the way. :) Spent a bit much on the Japanese version before even realising that it got localized under a different title.

Ok, I finally got the cartridge and dumped it.
I was almost right with everything (except for mirroring and some pins order)

By connecting PPU-A13 to the CHR register bank select, they got for free 1kB CHR banking and versatile mirroring control (can assign 0/1 for any of nametable)

Code: Select all

Bus-conflicts: no

Mirroring: 
  $2000   $2400   $2800   $2c00

Btw. The masks are really important, as the ROM writes to non primary register adresses (for example $f018, $c003)
